I’ve been trying to use RTX to get world position of each pixel in the rendered image, the code is based on a plugin sample from FluffyBunnyO.
I’ve encountered some accuracy issues because in the plugin sample the shader does not use the depth texture in order to calculate the ray origin and there for the ray origin is not accurate.
I’ve tried to pass on to the shader SceneDepthTexture by copying code from unreal engine but I’ve got a linkage error for function GetSceneTextureParameters.
I’ve checked the signatures of the function in Renderer.dll and I could not find any reason for this error.
Plugin code is here: Plugin Code
FluffyBunnyO tutorial is here: How to Create a Custom Ray Tracing Shader as a Plugin
Thanks.
Tamir.
